Energy-saving heavy water treatment and supply system {ENERGY-SAVING TYPE WASTEWATER RECLAIMING AND SUPPLYING SYSTEM}

The present invention relates to a domestic sewage sewage system for purifying and recycling sewage with low pollution in domestic sewage. More specifically, a heavy water treatment facility for purifying domestic sewage in the middle floor of a high-rise building is provided. After collecting and purifying low-pollution household sewage generated from the upper layer of the installed layer, the heavy water treatment facility is divided into the upper and lower layers of the installed layer to save the electric energy by supplying heavy water. The present invention relates to an energy-saving heavy water treatment and supply system with minimal initial capital investment.

In general, heavy water refers to water that is used once or repeatedly in any form.

In addition, the Wastewater Reclamation and Reusing System refers to a facility that reprocesses and supplies the tap water once used so that it can be recycled into domestic water and industrial water.

Living sewage (生活 下水) is a sewage generated by incidental to the daily life of a person, it is water mixed with various liquid or solid wastes generated in the kitchen bathroom bathroom. In particular, domestic sewage contains many organic compounds and detergent components. The main components of organic compounds are protein fat carbohydrates and their decomposition products of plants and animals. When they enter rivers, the biochemical oxygen demand (BOD) in water increases, and rivers and lakes lose their self-cleaning ability. Synthetic detergents do not decompose well and form bubbles in the water to block sunlight, and the phosphate component of detergents is an important cause of water pollution by causing eutrophication of lakes and streams.

The present invention purifies such living sewage, sewage toilet water, air conditioning cooling water, cleaning water, car wash water, sprinkling water, landscaping water (pond, fountain, etc.), sewage sewerage system (Domestic Sewage) to be reused, such as fire water Reclamation and Reusing System).

Figure 6 is a conceptual diagram showing an example of the domestic sewage sewerage system according to the prior art. As shown, the water system 100 according to the prior art is largely composed of a raw water collection facility 500, a heavy water treatment facility 600 and a heavy water supply facility (700).

The raw water collecting facility 500 is a facility for collecting the sewage with low pollution discharged from the wash basin 231, the bathtub 232, the washing machine 233, etc., and the heavy water treatment facility 600 purifies the collected household sewage. The water treatment facility 700 is a facility for supplying heavy water to a flush toilet 235 through a high weight water reservoir 710 installed on the roof of a building.

According to the prior art, the building is provided with a water supply facility 200 and a sewerage system 300 separately from the water supply system 100. The water supply facility 200 supplies the tap water supplied from the outside to the wash basin 231, the bath 232, the washing machine 233, the kitchen 234, and the like through the high water reservoir 210 installed on the roof of the building. And the sewerage system 300 discharges the sewage with high pollution discharged from the kitchen 234, the flush toilet 235 to the outside.

6 shows an example of an individual circulation type water system. That is, the sewage water system is classified into an individual circulation method, a local circulation method, and a wide area circulation method according to the location of the heavy water treatment facility 600 and the user (eg, a building).

The individual circulation method is a method of treating wastewater generated in the building by itself and using it for flush toilet water, cooling water, and cleaning water. The regional circulation method is larger than the individual circulation method, and it collects the wastewater from several buildings in one place, treats it, and supplies the treated heavy water back to each building. In addition, the wide area circulation system purifies the effluent generated from the large sewage treatment plant and supplies it to each building. Therefore, if the local water circulation system and the regional water circulation system are constructed, the water saving effect can be great, but the initial investment cost is very large and a large amount of energy is used to supply heavy water.

On the other hand, the individual water circulation system has a merit that the initial facility investment is low and energy is not required to supply heavy water because the heavy water treatment facility 600 and the facility using heavy water (building or flush toilet) are very close. In other words, in order to expand the distribution of the water system, various problems such as hygiene, operation and maintenance have to be solved, but the most important problem is economical efficiency. In this regard, the individual circulation method, which is very close to the heavy water treatment facility and the facility using heavy water, is more economical than the regional circulation system or the regional circulation method.

However, even in the conventional water circulation system of the individual circulation method, the heavy water treatment facility 600 is installed in the basement of the building, and the heavy water treated in the heavy water treatment facility must be pumped to the roof of the building to supply a lot of energy. In addition, in order to supply heavy water, it is necessary to install a separate pipe from the existing water pipe, so there was a problem that a lot of initial investment and maintenance costs are required.

The present invention is to solve the problems according to the prior art, the main object of the present invention is to install a heavy water treatment facility installed in a high-rise building, such as apartments, offices and commercial buildings in the middle floor of the high-rise building, raw water collection facilities and Energy-saving type that can minimize the investment of facilities by minimizing the size of heavy water supply facilities, reduce the energy required for the supply of heavy water, and reduce the operating costs by deactivating the sludge discharge facilities for discharging sludge from the heavy water treatment facilities. It is to provide a heavy water treatment and supply system.

In addition, the present invention is to provide an energy-saving heavy water treatment and supply system that can minimize the cost of purification by selectively recycling only high quality sewage of low pollution generated in high-rise buildings.

It is possible to provide an economical water supply system that can minimize the cost of water treatment by selectively recycling only high quality sewage with low quality.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment of the energy-saving heavy water treatment and supply system according to the present invention.

First, FIG. 1 is a schematic diagram showing an example of an energy-saving heavy water treatment and supply system including a heavy water treatment facility installed in an intermediate floor of an apartment or office or commercial high-rise building.

As shown, the energy-saving heavy water treatment and supply system 10 according to the present invention includes a heavy water treatment facility 60 installed in the middle floor 3 of a high-rise building 1, such as an apartment, an office or a commercial building. Heavy water is supplied to the upper heavy water supply facility 70 installed to supply the heavy water to the upper layer of the intermediate layer 3 in which the heavy water treatment facility 60 is installed, and the lower layer of the intermediate layer 3 to which the heavy water treatment facility 60 is installed. Raw water collecting facility (50) for supplying the downstream sewage water supply facility (80) installed to supply and the domestic sewage with low pollution in the domestic sewage drained from the upper layer of the intermediate layer (3) to the heavy water treatment facility (60). And, the living sewage with high pollution drained from the upper layer of the middle layer (3), the heavy water treatment facility 60 is installed, the various sludge discharged from the heavy water treatment facility 60 and the heavy water treatment facility 60 is installed Drained from the lower layer of the middle layer It comprises a sewage drainage facility 30 for draining the living sewage. In addition, the high-rise building 1 further includes a water supply facility 20 for supplying tap water to various water facilities such as a washbasin, a bath, a washing machine, and a sink provided in each floor of the high-rise building 1.

In the present invention, the upstream heavy water supply facility 70 includes an upstream heavy water supply pipe 72 and a heavy water supply pump 73. The upstream heavy water supply pipe 72 is similar to a conventional water supply pipe, and connects each of the flush toilets located on the upper floor of the middle floor where the heavy water treatment facility 70 and the heavy water treatment facility 70 are installed. In addition, the upward heavy water supply facility 70 may further include a high weight water reservoir 71 installed on the roof of the high-rise building 1 and connected to the upward heavy water supply pipe 72.

The downstream heavy water supply facility 80 includes a downward heavy water supply pipe 82 connecting each of the flush toilets located on the lower floor of the middle floor where the heavy water treatment facility 70 and the heavy water treatment facility 70 are installed. . In addition, the raw water collecting facility 50 connects each of the water facilities such as a wash basin, a washing machine, a bath tub, a sink, and the heavy water treatment facility 70 located on the upper floor of the middle floor where the heavy water treatment facility 70 is installed. Raw water collection pipe 52 is made. In addition, the sewage drainage facility 30 is composed of a sewage pipe 32 as in the prior art.

As shown, the energy-saving heavy water treatment and supply system 10 of the present invention is characterized in that the heavy water treatment facility 60 is installed in the middle floor 3 of the high-rise building 1. Recently, since most apartments or business buildings being built are high-rise buildings of 10 or more floors, the energy-saving heavy water treatment and supply system 10 according to the present invention may be applied to most apartments and business buildings.

The energy-saving heavy water treatment and supply system 10 of the present invention divides the high-rise building 10 into an upper layer and a lower layer, and cleans and recycles only living sewage having low pollution discharged from the upper layer. In residential apartments, for example, large amounts of low-pollution household sewage are discharged in the morning and evening from washbasins, bathtubs, washing machines and kitchens. Therefore, even if only the sewage with low pollution discharged from the upper layer can be purified to flush toilet water, air conditioning cooling water, cleaning water, fire fighting water and the like. As in the prior art, when all the living sewage drained from the entire high-rise building 10 is purified, not only the heavy water treatment cost increases but also heavy water is excessively produced, resulting in low economic efficiency.
On the other hand, the pollution degree of domestic sewage used for heavy water treatment in the present invention is relative. That is, when the capacity of the heavy water treatment facility 60 is sufficient or the overall pollution degree of the living sewage generated is high, the degree of pollution of the living sewage used for heavy water treatment may be increased, and conversely, the capacity of the heavy water treatment facility 60 may be small or generated. If the sewage of sewage is generally low, the pollution of sewage used for heavy water treatment is lowered. Therefore, low sewage living sewage and high pollution sewage are subjectively selected for each building.

Thus, the present invention is to install the heavy water treatment facility 60 in the middle layer (3) of the high-rise building (1), and to treat only the living sewage with low pollution generated in the upper layer with heavy water to supply the whole high-rise building (1) will be. Therefore, the water supply system of the prior art should install the raw water collecting facilities throughout the building, the present invention is installed only in the upper part of the building. In addition, the conventional water supply system should pump all of the heavy water to the roof of the high-rise building, but the present invention pumps only the heavy water needed in the upper part to the rooftop and supplies the rest to the lower layer by using gravity to reduce the capacity of the heavy water supply pump and consume energy. You can also save. In addition, since only the sewage with low pollutants drained from the upper part is sorted and purified, it is possible to reduce the size of the heavy water treatment facility and to reduce operating costs such as chemicals and electricity.

As described above, the present invention provides an economical water supply system by providing a heavy water treatment system by installing a heavy water treatment facility 60 on the middle floor 3 of a high-rise building such as a high-rise apartment 1 to reduce the initial investment and operating costs. The distribution of deuterium systems can be expanded.

Meanwhile, the heavy water treatment facility 60 installed in the middle floor 3 of the high-rise building 1 should be smaller and easier to maintain and hygienic than the conventional heavy water treatment facility. In general, the treatment of heavy water can be divided into biological, physical, bio-physical, chemical treatment technology. Therefore, various types of heavy water treatment facilities can be developed depending on the treatment technology selected. Representative treatment methods of heavy water treatment facilities include biological treatment and membrane treatment. The biological treatment method has a variety of types depending on the treatment method, and there are many applications in existing wastewater treatment facilities, but it has a disadvantage of taking up a lot of land. On the other hand, the membrane treatment method has the advantage that it is possible to secure high quality treatment water and can be installed in a relatively narrow site, but the installation cost is high. Accordingly, the present invention uses a relatively good quality of sewage as raw water, so that the biological treatment method can be used, but the physical-chemical treatment method can be mixed and miniaturized.

2 is a block diagram showing an example of a heavy water treatment facility 60 applied to the energy-saving heavy water treatment and supply system 10 according to the present invention.

As shown, the heavy water treatment plant 60 of the present invention is largely the screen tank 61, the flow adjustment tank 62, the raw water pressure pump 63, the upflow bioreactor 64, microstrainer 65, downward Ryu sand filtration tank 66, the disinfection facility 67, heavy water storage tank (68).

And the heavy water treatment facility 60 of the present invention is the sludge discharged from the screen tank 61, the flow adjustment tank 62, the upflow bioreactor 64, the microstrainer 65, the heavy water storage tank 68 and the like. 32) further includes a main sludge discharge pipe (69) for discharge.

Therefore, low-contaminant living sewage generated in the upper layer of the intermediate layer 3 in which the heavy water treatment facility 60 is installed is introduced through the screen tank 61 and the flow regulating tank 62, and the upflow bioreactor 64 After purifying through the microstrainer 65, the downflow sand filtration tank 66, the disinfection facility 67, and the like, it is temporarily stored in the heavy water storage tank 68.

The heavy water stored in the heavy water storage tank 68 is supplied to the upper and lower layers of the high-rise building 1 through the upstream heavy water supply facility 70 and the downstream heavy water supply facility 80.

As shown, the screen tank 61 is provided with an inclined screen 162 to remove the medium-large contaminants. The flow adjustment tank 62 stores the incoming raw water so as to alleviate the load fluctuation of the raw water so that an effective biological treatment can be achieved. To this end, the flow rate adjusting tank 62 is composed of two tanks 62a and 62b for stable treatment, and flushes sludge settled in the lower part once a day or at an appropriate cycle to the sewage pipe. To be discharged. The upflow bioreactor 64 is a fixed bed bioreactor in which a fixed bed media 165 is installed therein as a reactor for removing organic matter using microorganisms. The raw water of the flow rate adjustment tank 62 is supplied to the lower portion of the upstream bioreactor condenser 64 by the raw water pressure pump 63, wherein the raw water conveying pipe to which the raw water pressurized by the raw water pressure pump 63 is transferred ( The injector 164 is installed at the 163 to allow the microbubbles of external air to flow into the upstream bioreactor 64 together with the raw water. Subsequently, the microstrainer 65 collects and removes fine sludge contained in the effluent flowing out of the upflow bioreactor 64. At this time, the sludge collected in the microstrainer 64 is backwashed to be discharged to the sewage pipe (32). The downflow sand filtration tank 66 removes fine particulate matter contained in the effluent. Subsequently, the disinfecting facility 67 removes bacteria or viruses contained in the effluent and allows a predetermined concentration of disinfectant to remain in the heavy water. The disinfection facility 67 is an ozone facility or a chlorine disinfection facility in consideration of ease of handling. In addition, if necessary, a chemical coagulation tank may be further installed at the front end of the downflow sand filtration tank 66.

On the other hand, the upper sludge discharge pipe (261a) is installed on the upper portion of the screen tank 61, the lower sludge discharge pipe (261b) is installed. Therefore, the large contaminants that do not pass through the inclined screen 162 are discharged to the sewage pipe 32 through the upper sludge discharge pipe 261a, but passed through the inclined screen 162 but settled to the bottom of the screen tank 61. The sediment is discharged to the sewage pipe through the lower sludge discharge pipe (261b). At this time, the upper sludge discharge pipe (261a) is always open to be able to immediately discharge the large contaminants caught on the inclined screen (162). On the other hand, the lower sludge discharge pipe 261b opens when the screen tank 61 reaches the minimum water level. To this end, the screen tank 61 is provided with a first water level meter 263a for sensing the water level, and the lower sludge discharge pipe 261b has a first control valve 264a interlocked with the first water level meter 263a. It is provided. For example, when raw water flows into the screen tank 61, the first control valve 264a is closed, and when raw water does not flow into the screen tank 61, the raw water flows into the flow regulating tank 62. As the water level is lowered, the first control valve 264a interlocked with the first water level meter 263a is opened to discharge the sediment at the bottom of the screen tank 61 to the sewage pipe.

In addition, a hopper portion 265 is formed at a lower portion of the flow regulating tanks 62: 62a and 62b, and a stream portion 266 is formed at an upper portion thereof. The hopper portion 265 is formed with an inclined surface so that the sediment is collected in the middle of the flow control tank, the source portion 266 is formed in the form of a water channel on the inner surface of the flow control tank so that the floating water on the surface. The hopper portion 265 is provided with a settling sludge discharge tube 267, the scum discharge portion 266 is provided with a scum discharge tube 268. Therefore, scum or float floating on the water surface of the flow rate adjustment tank 62 is discharged to the sewage pipe through the scum discharge pipe 268 after being discharged to the source 266. In addition, the precipitate precipitated in the hopper unit 265 is discharged to the sewage pipe through the sedimentation sludge discharge pipe (267). At this time, the scum discharge pipe 268 is always open to immediately discharge scum or suspended matter, and the sedimentation sludge discharge pipe 267 measures the water level of the flow regulating tank 62 so as to open only when the minimum water level is reached. It opens and closes by the 2nd control valve 264b which communicates with the measuring device 263b.

In addition, a hopper 272 and a surplus sludge discharge pipe 273 are installed below the upflow bioreactor 64. At this time, the surplus sludge discharge pipe (273) is the third water level measuring instrument (263c) for measuring the water level of the upflow bioreactor (64) so as to open when the minimum water level is reached and the third water level meter (263c) interlocked with the It is opened and closed by the three control valves 264c. Therefore, excess sludge such as a biofilm detached from the fixed-bed media 165 is periodically discharged to the sewage pipe through the excess sludge discharge pipe 273. In addition, the hopper portion 282 and the sediment discharge pipe 283 are provided in the lower portion of the heavy water reservoir 68. The sediment discharge pipe (283) is the fourth control valve (264d) in conjunction with the fourth water level meter (263d) for measuring the water level of the heavy water reservoir (68d) to open when the water level of the heavy water reservoir (68) reaches the minimum level. It is opened and closed by.

As described above, the heavy water treatment plant 60 according to the present invention includes a screen tank 61, a flow adjustment tank 62, an upflow bioreactor 64, a downflow sand filtration tank 66, a heavy water storage tank 68 or Discharge pipes for discharging the contaminants, sediment, sludge, suspended solids, etc. generated in the chemical flocculation tank is provided, these discharge pipes are connected to the sewage pipe 32 through the main sludge discharge pipe (69). Therefore, the heavy water treatment facility 60 of the present invention can discharge the contaminants, sludge, etc. to the sewage pipe 32 without using additional power or energy.

On the other hand, the main sludge discharge pipe (69) is installed to be inclined downward at a predetermined angle to prevent the backflow of sewage, and to easily discharge the contaminants, sludge, etc. by force by gravity. In addition, at the tip of the main sludge discharge pipe 69, a odor preventing lid for preventing odor of the sewage pipe 32 from rising is rotatably installed.

Subsequently, the screen tank 61, the microstrainer 65, and the downflow sand filtration tank 66 according to the present invention include a backwash water supply pipe 285: 285a, 285b, 285c and a backwash control valve for periodic backwashing or flushing. 284: 284a, 284b, and 284c. For example, a plurality of backwash nozzles 286: 286a and 286b are installed below the inclined screen 162 of the screen tank 61 and the microstrainer 65. The backwash water supply pipe 282 is connected to the upward heavy water supply pipe 72.

Therefore, when inflow water does not flow into the screen tank 61 or the microstrainer 65, when the backwash control valves 284a and 284b are opened, heavy water in a predetermined pressure state is injected through the backwash nozzle 286. The foreign substance caught on the inclined screen 162 or the microstrainer 65 is separated and discharged into the sewage pipe. In addition, by opening the backwash supply pipe (284c) is connected to the lower portion of the downstream sand filtration tank 66 it is possible to periodically filter the sand layer. In this case, a backwash water discharge pipe 287 for discharging backwash water is installed at an upper portion of the downflow sand filtration tank 66.

As described above, in the heavy water treatment facility 60 according to the present invention, a backwash water supply pipe 285 is connected to the screen tank 61, the microstrainer 65, and the downflow sand filtration tank 66, and the used backwash water is used. The backwash water discharge pipes 287a, 287b, and 162a for discharge are connected to the main sludge discharge pipe 69. As described above, the present invention can be configured to be capable of supplying and discharging backwash water without power, thereby facilitating maintenance and reducing operating costs, thereby increasing economical efficiency.

In general, toilet water is mixed with the living sewage discharged from the high-rise building (1). However, the domestic sewage used in the energy-saving heavy water treatment and supply system 10 of the present invention is excluded from flush toilet washing water. In other words, when using the sewage containing the flushing wash water as raw water can be collected in a single pipe, there is an advantage that the pipe installation cost is reduced, but there is a possibility that bacteria or viruses exist in the flushing wash water and the water is high because of high pollution If the cost rises and it is installed on the middle floor of a building, bad smell can occur. Therefore, the present invention is economically and emotionally preferable not to use flush toilet washing water and high concentration sewage.

On the other hand, kitchen drainage discharged from the sink of the kitchen has a large difference in the degree of pollution of the sewage according to the step of using water. For example, there is a large variation in the degree of pollution of sewage that is drained according to the purpose of use of water, such as when cleaning food-stained dishes in a sink using detergent and when cleaning vegetables or fruits. In addition, even in the case of the washing drainage discharged from the washing machine, the initial washing drainage has a high organic matter concentration and a high concentration of oil components or surfactants, which requires a lot of treatment costs, but the wastewater generated in the rinsing step has a very low pollution. Therefore, it is preferable that the wastewater generated in the kitchen or the washing machine is selectively separated and used as raw water for reuse according to the use stage.

Sink drainage from sinks and bathtubs accounts for 10-30% of the total sewage and the water quality is relatively good. In particular, the wash water drainage generated in accommodation facilities such as hotels and inns is very good in terms of quantity and water quality, so it can be reused only by simple physical and chemical treatment. However, when washing the cleaning mop in the washbasin, it contains a substance that interferes with the reuse, such as detergent, floor wax, oil components, surfactants, it is preferable to selectively separate and use it as raw water for reuse.

Accordingly, the energy-saving heavy water treatment and supply system 10 of the present invention is provided with sewage separation means 90 at the tip of the raw water collection pipe 52. Figure 3 shows a preferred embodiment of the sewage separation means, Figure 3a shows a manual sewage separation means, Figures 3b and 3c shows an automatic sewage separation means.

Referring to Figure 3a, the manual sewage separation means (90a) is to be applied when the difference in the degree of pollution of the drain according to the use stage of the water, such as a washing machine or sink, two drain pipes are installed in the sink, washing machine. Therefore, according to the water use phase, the user discharges the high polluted sewage into one drain pipe, and the low polluted sewage is discharged into the other drain pipe so that the high polluted sewage is drained into the sewage pipe 32 and the low polluted sewage is the raw water collection pipe. To 52. This method has the trouble of installing two drain pipes in advance in a washing machine or a sink and discharging them according to the pollution degree when the user uses water.

On the other hand, the automatic sewage separation means (90b) shown in Figure 3b is installed only one drain pipe where the living sewage, such as wash basin, bathtub, sink, washing machine, etc., the pollution degree measuring sensor is provided for the living sewage drained through the drain pipe The sewage separation device 190 is classified into a high polluted sewage and a low polluted sewage, the high polluted sewage is drained to the sewage pipe 32, the low polluted sewage is discharged to the raw water collection pipe 52.

In addition, the automatic sewage separation means (90c) shown in Figure 3c is to be used where the low-contamination domestic sewage, such as wash basin or bathtub, is installed, the sewage separation device 190 on the raw water collection pipe 52 When the sewage with low pollution degree is drained as it passes, and if the sewage with high pollution degree is drained and then to be discharged to the sewage pipe (32).

At this time, the sewage separation device 190 is a raw water inlet (divided by a separation tank 191 having a closed space of a predetermined size, the partition 191 installed inside the separation tank 191 ( 192 and two raw water discharge parts 194: 194a and 194b, a pollution degree measuring sensor 196 installed at the raw water inlet 192 to measure the pollution level of raw water, and connected to the pollution degree measuring sensor 196 And door driving means 199 for selectively opening and closing two doors 197 for opening and closing a passage connected to the two raw water discharge parts 194.

Subsequently, Figure 4 shows another embodiment of the energy-saving heavy water treatment and supply system of the present invention, in particular, further installed underground water reservoir 75 in the basement of the high-rise building (1). As shown, since the rest of the configuration of the present embodiment is the same as the above embodiment, the same reference numerals will be given and detailed description thereof will be omitted.

 The underground heavy water reservoir 75 is connected through the heavy water inlet pipe 76 to store the remaining heavy water used in each floor of the high-rise building (1).
